Jetta V6-2.8L (BDF) (2002)
-
Measure resistance from throttle valve drive between terminals 3 and 5
Specification: 1.0 to 5.0
If the specification is not obtained:
-
Replace Throttle Valve Control Module -J338-, item 6.
-
Check DTC memory, repair malfunctions if necessary and then erase DTC memory. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes
-
Adapt Motronic Engine Control Module (ECM) -J220- to Throttle Valve Control Module -J338-.
-
Read readiness code. If the DTC memory has been erased or the Motronic Engine Control Module (ECM) -J220- was disconnected from battery
positive (B+), the readiness code must be generated again.
See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
If the specification is obtained:
-
Check voltage supply of Throttle Valve Control Module -J338- and wiring to control module.
-
Check Throttle Position (TP) sensor:
If the voltage supply and wiring are OK.:
-
Replace Motronic Engine Control Module (ECM) -J220-.
-
Check DTC memory, repair malfunctions if necessary and then erase DTC memory. See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/Reading Diagnostic Trouble Codes
-
Erase learned values and adapt Motronic Engine Control Module (ECM) -J220- again.
-
Read readiness code. If the DTC memory has been erased or the Motronic Engine Control Module (ECM) -J220- was disconnected from battery
positive (B+), the readiness code must be generated again.
